l Atfuelinr. Information JULY 1987 Unit 1 j

Unit 1 was placed on administrative hold in March 1985 to resolve TVA and NRC concerns. The uadt also began its sixth refueling on June 1, 1985, with a scheduled restart date to be determined. The sie.th refuell'ng will involve loading 8x8R (retrofit) fuel assemblies into the core.

The prior-to-startup unit 1 items are environmental qualification of electrical equipment (10CFR50.49), torus modification (NUREG 0661), containment modifications (NUREG 0737), electrical changes,(Appendix R 10CF350p (all), MSIV modifications, modification of masonry walls (IEb'80-11), evaluation of the vent drain and test connections, VDTC, (LER 82020), valve modification i(Appendix J), HPCI concerns, modification of PCIS logic (LER 259/85009), replacement of plant process computers, seismic qualifications of piping (IEB 79-02/14), postaccident evaluation (NUREG 0737), RpS modifications (IE Notice 78-45), H 0 sample line modification (LER 81050), radiation monitors modification (LER 80033), EECW carbon to stainless pipe change out, and all NRC commitment items except Anticipated Transients Without Scram (ATWS) modifications which are scheduled for next outage.

There are 0 assemblies in the reactor vessel. The spent fuel storage pool presently contains 284 new assemblies, 764 EOC-6, 252 EOC-5, 260 EOC-4, 232 EOC-3, 156 EOC-2, and 168 EOC-1 assemblies. The present available cap 6 city

)

of the fuel pool is 1355 locations.

Unit 2 Unit 2 was shut down on September 15, 1984, for its fifth refueling outage with a scheduled restart date to be determined. On September 3, 1985, the unit Iwas plac'ed on administrative hold to resolve TVA and 4RC safety concerns. The

~

fifth refueling involves loading 8x8R (retrofit) fuel assemblies into the core.

The prior-to-startup unit 2 items are CRD SDIV piping modification (IEB 80-17),

environmental qualification of electrical equipment (10CFR50.49), torus modifications (NUREG 0661), containment mo(ification (NUREG 0737), electrical changes (Appendix R 10CFR50) (partial), MSIV modifications, modification of masonry walls (IEB 80-11), addition of feedwater nozzle temperature monitoring (NUREG 0619), evaltation of the vent drain and test connections, VDTC, (LER 82020), valve modification (Appendix J) (partial), D/G rpeed sensor i

There are 0 assemblies in the reactor vessel. At month end there were 304 new assemblies, 764 EOC-5, 248 EOC-4, 352 EOC-3, 156 EOC-2, and 132 EOC-1 assemblies in the spent fuel storage pool. The present available capacity of the spent fuel pool is 1481 locations. All HDRs have been installed in the pool-l with the exception of two.

Unit 3 Unit 3 was shut down on March 9, 1985, and placed on administrative hold to resolve various TVA and NRC concerns with a scheduled restart date to be determined. The sixth refueling outage has been scheduled for September 21, 1988, and involves loading 8x8R (retrofit) assemblies into the core and ATWS modifications. The prior-to-startup unit 3 items are environmental qualifica-tion of electrical equipment (10CFR50.49), containment modifications (NUREG 0737), electrical changes (Appendix R 10CFR50) (all), MSIV modifica-
